Struct VarintResult 

pub struct VarintResult {
    pub next_pos: usize,
    pub varint_gar: Option<Vec<u8>>,
    pub varint: Option<u64>,
    pub varint_ohb: Option<u64>,
}

Result of parsing one protobuf varint from a byte slice.

Mirrors the Python Varint class in lib/varint.py.

Exactly one of varint or varint_gar is Some:

• varint_gar is Some when the varint is truncated (buffer ends before the terminator byte) or exceeds 64 bits.
• varint is Some for a successfully decoded varint.
• varint_ohb counts trailing non-canonical (overhung) bytes: set when the terminating byte is 0x00 preceded by one or more 0x80 bytes.

Fields

next_pos: usize

Byte position immediately after the parsed varint.

varint_gar: Option<Vec<u8>>

Some(raw_bytes) when the varint is garbage (truncated / too large).

varint: Option<u64>

The decoded varint value (valid only when varint_gar is None).

varint_ohb: Option<u64>

Number of non-canonical overhang bytes (valid only when varint_gar is None).
